You can assemble the Firebird XL and have it flying almost as soon as you get it home from the shop. The whole assembly process takes less than 1 hours, and you may need an hour or two to charge up the battery for the first flight. The included instructions take you step-by-step through the assembly process and offers some useful flying tips. So even if you've never flown an R/C airplane in your life, you can experience a successful start on your own. The XL's larger 40" wingspan, bigger fuselage, and more powerful Mabuchi 400 motor allow it to be flown in windier conditions. Beginners shouldn't fly it with any more wind than about 8 mph, but experienced pilots should be able to fly the XL with confidence in 12-15 mph winds. Climb performance is outstanding-almost twice that of the original Firebird XL, in fact, in several of our test flights, a straight-out climb at full throttle for about 45 seconds would put the Firebird XL at about 800 feet and almost out of sight. With this much excess power, it was easy to loaf along at 1/2 to 3/4 throttle without losing any altitude at all. To go with the increase in size and power, the Firebird XL 400 features a larger, redesigned V-tail with bigger control surfaces. In addition to providing more authority in turns with the power on, the beefy tail surfaces produce better turn performance with the power off too. This is appreciated most during an approach to landing or when thermalling with the power off. Instead of using wire, high-test nylon fishing line is connected to control horns on top of the control surfaces. A rubber band on the bottom of the V-tail mounting bracket balances out the tension from the nylon lines and helps keep the control surfaces level when not in use. |
